Gravitational lensing by a stable rotating regular black hole
Chen-Hao Xie, Yu Zhang, Qi Sun +2
Recent observational data from the Event Horizon Telescope (EHT) collaboration provide convincing realistic evidence for the existence of black hole rotation. From a phenomenologic…
Shadow of Kerr black hole surrounded by a cloud of strings in Rastall gravity and constraints from M87*
Qi Sun, Yu Zhang, Chen-Hao Xie +1
Motivated by the first image of a black hole captured by the Event Horizon Telescope (EHT), there has been a surge of research using observations of black hole shadows to test theo…
Rotating and twisting charged black holes with cloud of strings and quintessence as a particle accelerator
Qi-Quan Li, Yu Zhang, Qi Sun +1
In this paper, we study the effects of the rotation parameter , the twist parameter , the string cloud parameter , the quintessence state parameter and the charge…
Thermal fluctuation, deflection angle and greybody factor of a high-dimensional Schwarzschild black hole in STVG
Qian Li, Yu Zhang, Qi-Quan Li +1
In this work, we study the thermal fluctuation, deflection angle and greybody factor of the high-dimensional Schwarzschild black hole in scalar-tensor-vector gravity (STVG). Based…
Weak gravitational lensing by an ESTGB black hole in the presence of a plasma
Qian Li, Yu Zhang, Zhi-Wen Lin +2
This paper is devoted to studying the weak-field gravitational lensing properties of a 4D ESTGB black hole, which is surrounded by the plasma medium. The effects of the magnetic ch…
Rotating Bardeen black hole surrounded by perfect fluid dark matter as a particle accelerator
Qi-Quan Li, Yu Zhang, Qian Li +1
We study the event horizon of a rotating Bardeen black hole surrounded by perfect fluid dark matter and the black hole as a particle accelerator. The black hole is represented by f…
Quasinormal modes, Hawking radiation and absorption of the massless scalar field for Bardeen black hole surrounded by perfect fluid dark matter
Qi Sun, Qian Li, Yu Zhang +1
We study the quasinormal modes, Hawking radiation and absorption cross-section of the Bardeen black hole surrounded by perfect fluid dark matter for a massless scalar field. Our re…
